Which datatype is used for date in sql server

Anyway, the better way to know is to test and check. Here is a sample result when running the following query. This query gives back the first 4 bytes of previous value: 0xA We deduct that 00F9C8AE is the time value for We will modify the second query in previous subsection and proceed the same way.

As expected, we get back following value: 0x00F9C8AE. It returns Well this number does not seem to be the number of seconds since If we divide the total above by 3. So, for an obscure reason, SQL Server « counts » by 3.

From now on, we will focus on practical cases where DateTime is a limitation and should absolutely be avoided. When it would be done, I could generate reports on these data and even correlate each record with the results of the importation of another data source. This process had to be designed so that it could run regularly.

To do so, it would store timestamp value of last imported record at the end of execution. Once another run is launched, it would take back this timestamp and filter out data from its data source so that it only takes care of records after that timestamp. The contents of the log was prepended with timing information with a millisecond precision.
